The worship of "Mother" is a commonality among many civilizations, which often maternalize and personify concepts like the world and the earth, hence the emergence of the Mother Goddess worship across diverse civilizations.
In simple terms, every civilization has a mother, and even if they don't, they'll acknowledge one—everyone wants to be looked after by a mother (Freud: I really didn't say this)
In the Multi-universe, how many Deities might believe that the call for the Mother Goddess is meant for themselves, not to mention those followers who only refer to their gods as "mom" or "dad"?
A Deity's "name" or "title" always carries specific significance; false declarations are easily debunked.
Most of the time, the followers of these Deities refer to them with appellations like, "Mother Goddess," "Great XX," or "Kind Mother of Ten Thousand Spirits."
